Commuters on the Wiggle got a Bike to Work Day surprise this morning: green-backed sharrows guiding bicycle riders through the intersection of Steiner and Waller Streets.

The “sharrows were painted VERY early this morning and they are permanent,” says a post on the SFMTA’s Livable Streets Facebook page[2]. Agency staff wrote that more will be added “as wayfinding guides all through the Wiggle” along each block and through other intersections in coming weeks.
